Abstract: A display device of the present disclosure includes a substrate, a lens layer including a lens, a light-transmitting layer that contacts a lens surface of the lens, and has translucency, a pixel electrode disposed between the substrate and the lens layer, and a color filter disposed between the pixel electrode and the lens layer. The lens is disposed so as to correspond to the pixel electrode. A refractive index of a constituent material for the lens is lower than a refractive index of a constituent material for the light-transmitting layer.

Abstract: An image display device of the present disclosure includes an image light generating device, a first, a second, a third, and a fourth optical unit. A first intermediate image is formed between the first and the third optical unit. A pupil is formed between the second and the fourth optical unit. A second intermediate image is formed between the third and the fourth optical unit. An exit pupil is formed at an opposite side of the fourth optical unit from the third optical unit. The image light generating device includes a first, a second, a third light emitting panel, and a color synthesis element. The color synthesis element is constituted of a cross dichroic prism including a first and a second dichroic film that intersect with each other. Each of the first and the second dichroic film does not have a polarization separation characteristic.

Abstract: A display unit includes a mounting member mounted on a first accommodation member configured to accommodate a lens group including an objective lens and an eyepiece, a display element that emits video light, a first deflection member that deflects the video light from the display element, and a second accommodation member configured to accommodate the display element and the first deflection member. The second accommodation member is mounted on the first accommodation member, such that the first deflection member is disposed on an axis of the lens group, by the mounting member. When the first deflection member is disposed on the axis of the lens group, an axis of the video light deflected by the first deflection member overlaps with the axis of the lens group.

Abstract: A display module includes a display element, a light-guiding optical system forming an exit pupil, and an optical member including a light incidence surface and a light emission surface. The light-guiding optical system is an eccentric optical system, and includes first and second incidence areas on which the image light emitted from the light emission surface is incident. The optical member is disposed, correcting an inclination of the light emission surface with respect to the light-guiding optical system such that an variation amount in an incidence angle of the image light with respect to the first incidence area, before and after the light emission surface is inclined, is greater than an variation amount in an incidence angle of the image light with respect to the second incidence area.
